Bathymetric map (IBCAO 3.0) showing the LOMROG III ship track (orange) and fieldwork north of Greenland as part of the Continental Shelf Project of the Kingdom of Denmark from 2006 to 2012.Yellow line – LORITA seismic refraction lines (2006),...
Overview map showing the main part of the bathymetric data acquired during LOMROG III. Numbers indicate the four profiles covering the flank of the Lomonosov Ridge facing the Amundsen Basin. Data acquisition (profiles 1 and 2) was focused on the...
Seismic line acquired in the Amundsen Basin showing the overall good data quality. Ocean gravity data reflect the bathymetry and density distribution of the oceanic crust and mantle. Low gravity values are related to low densities (sediments),...
Example of the rock samples gathered. Photo: Thomas Funck Rock samples dredged from the Lomonosov Ridge could yield valuable information on the origin of the ridge and could strengthen the argument for a natural prolongation of the...
CTD station map showing ship (S), expendable probes (X) and helicopter (H) ice stations recovered during LOMROG III. The oceanographic programme carried out during the cruise includes the collection of water column profiles with conductivity,...
